It isevident that this 'combinationflof gearing communicates a very powerfuldriving action to the crank shaft gears 7 from the pulley 8. Y

Mounted on. the base 1 of-the frame is a bed 14, which extends over thetops of the crank chambers 2 and is supported at intervals intermediateits ends by downwardly projecting leg portions, which rest onthe top ofthe base at the sides of said chambers, as. best shown in Fig. 1. Thetop portion of the bed 14, while extending throughout the length of theframe base .1 is narrowed in width and disposed centrally of the sideedges of said base, as best shown in Fig. 2.

= The'.base 1 and bed 14 are secured-together by vertical tie-rods 15, aplurality of which aredispo'sed at each side thereof and extend upwardtherefrom and support a frame The main or bottom slide of the press isdesignated 17 and is guided for vertical reciprocatory movements -by thetic-rods 15 wlth which it has sliding engagement. This slide is ofinverted U-shape in cross-section to adapt it to straddle'the narrowedtopportion of the bed 14, and has its legs resting 22, whichthreadthrough upwardly extendat their lower ends on blocks 18, one of which isdisposed'in the upper portion of 'eachcrank chamber 2 of the base and ispivotally carried by a pitman 19 that is mounted on the respective crankportion 4 of the crank shaft .3. It is thus evident that a turning ofthe crank-shaft 3' will cause vertical reciprocatory movements to beimparted to the main. slide 17 relative to the bed '14.

A die-shoe 20 is mounted on the top-of the slide 17 and in turnremovably carries a matrix die 21. The die 21 is held properlypositioned on the die shoe 20 by set/screws ing side flanges of the shoeand engage the respective sides of the die. The die 21 pref erably hasthe cavity thereof extending entirely therethrough so that the bottom ofthe opening is closed by the die-shoe.

23 designates the blank supporting pad which is of suitable size tofitthe cavityof the-matrix die and to have verticalmove- 'ments therein,the pad forming the bottom proper: of the die cavity when the die israised relative thereto.

The pad 23 is supported in stationary position relative to the pressframe by a plurality of pins or supports 24, which rest at' their lowerends on the top of the bed 14 and extendupward therefrom throughregisterguided by the crank sha anism briefly described comprlses aslide block 29,.which is mounted in suitable guide "ways provided'in theupper central portion ing openings'inthe slide 17 and die-shoe 20. Thepins 24 are of suitable length to support the upper edge of the pad 23slightly above the upper edge of the die 21 when the ,slide 17 is at thelimit of its downward movement, as indicated in Figs. 1, 2, 6, 7

and 9 and the upward movement of the slide is'the same in length as themaximum projection of the pins 24 above the die-shoe 20,

as is apparent by reference to the figures.

To-facilitate an accurate adjustment of the pins 24 relative to the diea wedge-member 25 is adjustably mounted on the top of the bed 14 inposition to support or receive the downward thrusts of the pins 24. Thiswedge member has its bottom, in the present instance, in dove-tailedengagement with the top of the bed for sliding movements the die 21 andmanner of mounting the same on the main slide may be changed as desired,

and also that the form of the pad 23 may be changed as desired, or asthe workto be performed may require, the construction shown being merelyillustrative of one form of the invention.

Theupper or blank-holder slide 28 is guided for verticalreciprocatory-movements above the main slide 1 and parts mounted thereonby the tie-rods 15, andhas its movements controlled, in-the presentinstance,'by a toggle mechanism similar to that described I in PatentNo. 1,089,558, dated March 10, 1914, said mechanism being connected toand t 3. This mechof the frame head 16 for vertical sliding movementsrelative thereto, as best shown in Figs. 3 and 4. Mounted in the framehead at opposite sides of the block 29 is a pair of transverse shafts30, each having an arm 31 project ng therefrom and-connected to therespective side of the slide block by a link 32. .At the ends of eachshaft 30, with- ,out the frame head, are provided crank arms 33 whichare respectively connected by outwardly extending links 34 to crank-arms35 projecting upward from the respective ends of rock shafts 36-, whichare mounted in'the end portionsof the frame head 16 at the under sidethereof.

The lower ng orrecession of the inatriX-die 21 relative to the pad 23 eansesan ejectionof-thework from the matrix die, as shown in Fig. 9,' therebyfacilitating a ren'ioval ot' .the work from 'the press. It is apparentthat the firm gripping of the bottom of the work between the blankholder and pad preblank and enables the edge of the central portions ofthe blank. In the modificationof the inventionillustrated in Figs. 12to20. (35 designates the base of the machine frame which is mountcd inany suitable manner on a supporting holder 60 and shapes the edges oftheblank A foundation (not sho wn) and 66 the frame head, which isconnected to'and rigidly supported by the frame sides 67. Said base andframe parts are also connected by a plurality of bolts or tie rods, 68.A bedplate 69is mounted on the top of the base 65"and, in the presentinstance, is directly supported by a pair of adjusting strips 70, 70,which are disposed lengthwise of the base and rest in uide ways providedon the top of the base or longitudinal adjustment lengthwise thereof.The strips 70 have their tops formed with successive tapered surfaceswhich coact with corresponding oppositely disposed tapered surfaces onthe under side of thebed-plate 69, as best shown at 71 in,, Fig. 12,whereby a longitudinal movement 'of the strips 70 relative to thebedplate effects a vertical adjustment thereof. The base 65, in thepresent instance, is shown as being of hollow formand the top edge ofeach-side wall thereof is provided with a race or guide-way 72- for oneof the adjusting strips 70. The adjusting strips 70, 70 are'c'onnectedat one end by a cross-bar 7 3, outwardly from which projects a rod 7 4.A

I worm-wheel 75 is threaded on the outer end portion of the rod 74 andis mounted in a bracket 76 on the adjacent frame side in a manner topermit a turning of the wheel but to prevent axial movements thereof. Itis thusfevident that a turning of the wormwheel 75 on the threaded rod74 will effect an adjustment of the bed-plate supporting strips 70, 70in one directlon or the other depending on the direction of turning ofthe wheel. A worm-shaft 77 is mounted in the bracket 76 with its worm inmesh with the worm-wheel 75 and is rovided at one end, withoutthe'bracket, with a hand control wheel 78'. A male die 79 of any desiredform is mounted on the top of the bedplate 69.

In the present form of my invention the crank-shaft 80 of the press ismounted on the head of the press. frame and, in the resent instance, hasW132i! of cranks rom which depend pitmen or connecting rods 81 that arepivotally connected to and carry the to die-carrying slide 82 of thepress.

This s ide, which is-hollow in form for the .pur ose hereinafterdescribed, has its end 'wor ing in suitableguides'in the sides 67 of thepress frame, whereby the slide is caused to have trueverticalreciprocatory move ments communicated thereto by the 81 when the crankshaft 80 is rotate as is well understood in the 'art. The matrix die 83of the press is carried-by the slide 82 on the bottom or undersidethereof in proper register with the male die 79. A blank-holder slide 84is.,,mounted for free reciprocatory movements within the die H carryingslide 82, being guided thereby, and T16 carries a blank lmlder pad atits under itmen side, saidpad being movabl disposed within I the cavityof the matrix ie. 83 and below the bottom portion of the die carryingslide 82 to which the matrix die is secured. The

blank holder pad 85 is spaced from the bottom of the slide 84 by aplurality of blocks 86, wlnch project up through registering openings 87provided in the bottom of the die carrying slide 82. The pad and'spac- Iing blocks 86 are rigidly secured to the bottom of the slide 84 by bolts88, one of which It .is therefore evident that the blocks 86 which arearranged to suit the form of the blank holder pad 85 may not be disposedin true alinement lengthwise of the slide 84* but may assume moreor'less of a1 zig-zag formation. Such arrangement of the blocks willnecessitate a placing of the blocks in differentially spaced relation tothe side edges of the slide 84 and in order to permit an adjustment ofthe blocks transversel of the blank holder for such purpose, the ase ofthe/blank holder is preferably broader than the blocks 86 to enable agreater or less transverse shifting of the blocks with -'re spect to theslide.

' The blank-holder slide 84 is directly carried by verticallydis osc'dadjusting screws 90, two being provi ed in the present instance, whichscrews thread into the top portion of the blank-holder slide and arerotat'ably carried at their up er ends by a vertically movable head 91.hishead is carried by a set of links 92, which are connected ,to pivotpins 93 on the head and form parts of a toggle mechanism which iscarried by the top portion 66 of the press frame and is operativelyconnected to a crank at one end of the shaft 80a This to gle mechanismis in all essential details t e same as 1 5 that described in connectionwith Figs. 1 to '11 of. the drawings, and will thereforenotboKdescribed. Each screw 90 carries-a worm wheel 94 within a portion ofthe head 91, and each of said wheels is in mesh with a respective wormwheel 95 on a shaft 96 that is'suitably journaled in the head 91lengthwise thereof. The shaft 96. has bevel-gear connection, as at 97,with a short shaft 98 that is mounted onone side portion of the head 91transversely thereof and carries a worm-wheel 99 ,at its outorrnd inmesh with a worm 100 on a shaft 101. \\'lileli"is mounted lengthwise ofthe head 91 in a bracket so 55 conform to the shape of the dies 79 End83. i
